Abstract

Conventionally, there is a description about stereophonically reproducing downloaded musical pieces or those stored on a memory card. A call speech is supported in monaural only. A realistic telephone call using stereo sound has been unavailable. The present invention aims at providing a cellular phone capable of a telephone call using stereo sound. The cellular phone terminal capable of speech communication with another information processing terminal. The cellular phone terminal is configured to comprise: a plurality of speakers for the speech communication; a receiver to receive a speech signal from a plurality of microphones of the other information processing terminal; and a processor to provide control so that the plurality of speakers can output the speech signal received by the receiver.

Claims (33)

1. A cellular phone terminal capable of speech communication with an information processing terminal, comprising:

a plurality of speakers for the speech communication;

a receiver to receive a speech signal supplied by a plurality of microphones of the information processing terminal; and

a processor to control each output of the plurality of speakers based on the speech signal received by the receiver, wherein

the plurality of microphones are arranged on left and right sides of the information processing terminal and the plurality of speakers are arranged on left and right sides of a display section; and

the processor provides control so that a left speaker of the cellular phone terminal outputs a speech signal which is supplied by a right microphone of the information processing terminal and is received by the receiver, and a right speaker of the cellular phone terminal outputs a speech signal which is supplied by a left microphone of the information processing terminal and is received by the receiver.

2. A cellular phone terminal, comprising:

a selector to set a call mode to a video telephone mode or a normal call mode;

a plurality of speakers for the speech communication;

a receiver to receive a speech signal supplied by a plurality of microphones of an information processing terminal;

a decompressor to decompress the speech signal received by the receiver; and

a processor to provide control to allow the plurality of speakers to stereophonically output a speech signal decompressed by the decompressor when the selector sets the call mode to the video telephone mode.

3. A cellular phone terminal capable of speech communication with an information processing terminal, comprising:

a plurality of speakers for the speech communication;

a plurality of microphones to input a speech sound;

a compressor to compress a speech signal supplied by the plurality of the microphones;

a transmitter to transmit a speech signal compressed by the compressor to the information processing terminal;

a receiver to receive a speech signal from the information processing terminal;

a decompressor to decompress a speech signal received by the receiver;

a processor to provide control to produce a speech signal decompressed by the decompressor; and

a distance sensor to detect a distance between the cellular phone terminal and a human body,

wherein the processor selects a call mode or a call format according to a distance detected by the distance sensor.

4. The cellular phone terminal according to claim 3 , wherein

the processor selects a normal call mode as the call mode when the distance detected by the distance sensor is determined to be smaller than a specified value and selects a video telephone mode as the call mode when the distance detected by the distance sensor is determined to greater than or equal to the specified value.

5. The cellular phone terminal according to claim 4 , wherein

the specified value is selectable.

6. The cellular phone terminal according to any of claims 2 and 3 , wherein

the plurality of speakers are movable via a connector section or a slider.

7. The cellular phone terminal according to any of claims 2 and 3 , wherein

the plurality of speakers are detachable via a docking hole.

8. The cellular phone terminal according to any of claims 2 and 3 , wherein

a first case body having a display screen and a second case body having an operation section are foldable at a hinge section; and

at least one of the plurality of speakers is provided on the first case body and at least one of the plurality of speakers is provided on the second case body.
